* config: move [ui] parsing in separate fileRobin Jarry2022-11-162-316/+345
| | | | | | | | | | | | | | | | | | | | | The config.go file is getting too big. Move the aerc.conf [ui] section parsing logic into a dedicated ui.go file. Add a defaultUiConfig() function to also get the default configuration values in a separate file. Extract fragmented bits of code in AercConfig.parseConfig() in a new AercConfig.parseUi() function defined in ui.go. Change parseUiConfig() into a UIConfig.parse() method. Change some methods receiver args to pointers to avoid unnecessary copies. No functional change. Signed-off-by: Robin Jarry <robin@jarry.cc> Acked-by: Moritz Poldrack <moritz@poldrack.dev>

* msgviewer: show error if MessageInfo has errorTim Culverhouse2022-11-091-2/+9
| | | | | | | | | | | | | | | | | MessageInfo structs can be returned from the workers with parser errors. MessageViews were previously prevented from opening if the error field was not nil, however the addition of message view splits have allowed these messages to have split views created. A panic can occur if a split is open and one of these messages is scrolled over. Prevent access to MessageInfo methods if the Error field is set. Display the error to the user in the split view. The partSwitcher will be nil if an error is set: check for this condition before calling it's methods.

* maildir: drain limit channel on parse error when sortingTim Culverhouse2022-11-091-0/+1
| | | | | | | | | | | | | | Commit 155f0c3f28a1 ("maildir/sort: get MessageInfos in parallel") added parallel parsing of maildir messages. The parsing is limitted to 2x the number of CPUs using a buffered channel. The channel is drained at the end of the parsing, however it is not drained if a parse error is encountered. With enough errors, this can lead to a deadlock. Drain the channel when an error occurs.

* maildir: always sort by at least uidTim Culverhouse2022-11-091-1/+7
| | | | | | | | | | | | | | | | | | | | Commit 29205fdd07c0 ("maildir/search: get MessageInfos in parallel") introduced parallel searching of maildir backends, which improves search and filtering performance. When no filter is specified, the search algorithm is still used with no criteria because the FilterCriteria field always contains "filter" as a minimum. With the new parallelized search, the message order becomes random. Only use the search algorithm if there is a filter specified. If a filter *is* specified and a sort order is *not*, the messages will go through the search algorithm and become randomized, but not sorted back in order. Always default to a UID order sort (the same as prior to this commit) when no sort order is specified.
